CWDM GBIC Module and SFP Module Description and Information
Parameters are specified over temperature and at end of life unless otherwise noted.
When shorter distances of single-mode fiber are used, it may be necessary to insert an in-line optical
attenuator in the link to avoid overloading the receiver.
